Calibrating the scale

A digital measuring unit (Multimeter), preferably with a 5-figure display, is
connected to the output of the module (current or voltage output). The
Multimeter should have a resolution of 0.01 mA in the current range so that
calibration to an accuracy of at least 0.05% can take place.
2.5

Zeroing the scale

The scale is now roughly zeroed (tared) with a high or low preload using the
microswitches, and fine adjustments are made using the potentiometer.
The scale is therefore fully unloaded and then the output signal is set to an
exact output current of 4.00 mA, for example, using the microswitch and
the potentiometer.
2.6 Calibrating the max. scale load, weighing range
Load the scale with a nominal weight (full load) and then adjust the
amplification using the microswitch (rough) and the potentiometer (fine)
until the Multimeter displays exactly 20.00 mA. Repeat procedure (items 5
and 6) several times. If only part of the nominal scale value is going to be
used, the amplification can be roughly modified by adjusting the
microswitch. For example, if only 50% of the nominal value is needed and
the load cell that is connected has a nominal characteristic value of 2mV/V,
the amplification microswitch is set to 1mV/V (i.e. 10mV) accordingly (see
table).

Scale ready for operation

The scale is now ready for operation.

*ATTENTION:
When the 0-10 Volt output is
being used, the "0-20/4-20mA"
selector switch must also be set
to 0-20mA !
